Replacing vs. Maintaining Legacy Systems
Search CIO, Wednesday, July 5,2023
Understanding issues such as which systems hinder organizational performance can help IT leaders decide which legacy systems to replace and which to maintain.
Few CIOs escape the complexity of deciding whether to maintain legacy systems or replace them altogether. The right choice, as with most things in life, is: It depends.
IT leaders might want to replace a legacy system because of outdated hardware, increased security risks or a desire to enable a digital transformation initiative. But replacing existing systems isn't always in the company's best interest. Legacy systems can remain in place if the existing system is reliable.
CIOs and IT leaders should consider the benefits and challenges of replacing vs. maintaining legacy systems.
